The log snippet clearly shows that it is fetchmail generating the message. For some reason, it cannot connect to the localhost IPv6 address for delivery via SMTP.
I believe the solution is either (a) to fix your fetchmail conf, or (b) to have postfix listen on IPv6 addresses.
the op posted this on the postfix list just now and was advised to check that postfix is configured to listen on ipv6. something along like having inet_protocols = all in /etc/postfix/main.cf should do it.
